A fellow I know called me about a problem with his '85 240. He said he had turned the ignition key to ON and then was distracted by a customer. After about 3 hours, he realized he was hearing a clicking sound from his 240. When he tried to start it, it was so flooded with gas that it was hydrolocked. The clicking sound was the fuel pump relay repeatedly clicking.

He pulled the plugs and got the gas out of the cylinders so the starter could turn the engine over. However, the ehgine would barely start and would die often. It would idle very poorly before it quit runnung. While the engine was running, he could feel the inlet hose to the fuel rail and it was pulsing in time with the clicking relay.

He tried the following: Replaced the fuel relay. There was no change. He disconnected the AMM and the engine would still not run.

What do you folks think the problem is? Is there something in the ECU which could be doing this?
